Lab 13 - Aspirin and Other Analgesics

You have been tasked to assess a new laboratory for safety issues. The lab has a large amount  of benzene, hydrochloric acid, phenol, sodium hydroxide and toluene. Describe the (5) potential  hazards that can be associated with each chemical above, as well as the methods to control their  potential hazards in the lab.

In this lab you are performing your first organic synthesis and safety information on all the materials you are using must be obtained. Companies are required to provide material safety data sheets (MSDS) for chemical compounds they sell. Please examine the MSDS for salicylic acid, available here. You will find GHS pictograms within the sheet that summarize the main hazards of this compound. The pictograms are essentially the same as the symbols on WHMIS labels, available here for reference. Based on the pictograms, whatare the main hazards for salicylic acid? Select as many answers as appropriate Select one or more: Acute oral or inhalation toxicity Flammable material Carcinogen Self-reactive substance Gas under pressure Corrosive Oxidizing material

In the middle of your experiment, a corrosive chemical accidentally spilled to your laboratory gown. What should be your best course of action? Select the correct response: Run to the school clinic immediately and seek fırst aid from the school nurse and/or physician. Call or text your parents about the incident and ask them for help. Take out your lab gown and use the emergency shower to flush out the spilled chemical that have reached your clothing and skin. Yell for help inside the laboratory room. Go to the sink and wash your laboratory gown to remove the spilled chemical.

PAP Chemistry-2903012-42100P-1/ Le Chatelier's Principle/ Lesson 128 2. Zinc (Zn) granules react slowly with dilute hydrochloric acid (HCI), but much faster if the acid is concentrated. Zn(s) 2HCI(aq)ZnCl2(aq) + H2(g) Zinc + Hydrochloric Acid Zinc Chloride + Hydrogen What causes the reaction to proceed faster with concentrated acid? The concentrated hydrochloric acid causes more hydrogen gas to be produced. The pressure of hydrogen gas molecules increases as concentration increases. The concentrated hydrochloric acid molecules move faster than in dilute acid. There are more collisions between the zinc and concentrated hydrochloric acid. PREVIOU

Eistrogens are female sex hormones, the most potent of which is B-estradiol. OH H,C но B-Estradiol In recent years, chemists have focused on designing and synthesizing molecules that bind to estrogen receptors. One target of this research has been nonsteroidal estrogen antagonists, compounds that interact with estrogen receptors and block the effects of both endogenous and exogenous estrogens. A feature common to one type of nonste- roidal estrogen antagonist is the presence of a 1,2-diphenylethylene with one of the benzene rings bearing a dialkylaminoethoxyl substituent. The first nonsteroidal estrogen antagonist of this type to achieve clinical importance was tamoxifen, now an important drug in the treatment of breast cancer. Tamoxifen has the Z configuration shown here. но NMe, NMeg ? B NMeg ? "NMe, ОН Tamoxifen Propose reagents for the conversion of A to tamoxifen. Note: The final step in this synthesis gives a mixture of E and Z isomers.
